What are best practices for radiation oncology patient and staff precautions with the COVID-19 pandemic?
COVID Update 1/30/21 Wow, it's been almost a year. Here are some updates from our practices at University of Maryland. We have successfully treated both PUIs and COVID+ patients at all of our practices. We have yet to have a patient to staff (or staff to patient) transmission. We do not break patien...
How do you approach treatment of a glioblastoma in pregnancy?
Glioblastoma during pregnancy could be treated safely (to mother and fetus) with certain precautions and modifications. Collaboration and consultation with the patient’s obstetrician are essential. External shielding over the patient’s abdomen during treatment will decrease the external scatter radi...
For an non-operative patient with IB1 cervical cancer, would you recommend RT alone or concurrent chemoRT for definitive therapy?
I usually favor RT alone as local control and the outcome is excellent unless they have adenocarcinoma, a suspicious pelvic node, or multiple high risk features (high grade with LVSI on bx).
What measures should we take regarding routine follow-up visits for well patients in surveillance during the coronavirus pandemic?
3-6 months.
How would you boost a high-risk prostate cancer patient who received standard fractionation treatment and is not able to get LDR boost given COVID-19?
I will assume for the sake of argument that he is also getting ADT as part of his treatment. If he has responded well to ADT (I like to see about a 90% drop in the PSA within 3 months), my preference would be to try to delay until it's reasonable from an infectious disease perspective to proceed wit...
How should you manage a coronavirus infected/suspected patient who is receiving radiotherapy and cannot interrupt or delay their cancer treatment?
Hi Everyone, I agree with all the comments—this is certainly a fluid situation. We have not had a confirmed COVID-19 case, but we have developed a plan. If it is deemed a known COVID-19 patient, and it is elected to continue treatment by the treating physician, the treatment will happen at the end o...
In the wake of the COVID-19 pandemic, are there any hypofractionated regimens (without concurrent chemotherapy) that could be utilized for head /neck cancer in a post operative setting?
A very recent paper by Eric Hall and David Brenner’s group (Shuryak et al., Int J Radiation Oncol Biol Phys 2019) is titled “optimized hypofractionation can markedly improve tumor control and decrease late effects for head and neck cancer”. Using a recently improved model, they concluded that an opt...
Are there scenarios that new visits/consults with patients can be done virtually amidst the COVID-19 outbreak?
Starting 3/16, we began offering lower-complexity / lower-risk patients the option of having a Tele-medicine consult vs re-scheduling to a later date. This offer has been extended broadly to all new consults at our facility when the provider indicates that s/he can extend comparable service virtuall...
How will the LORETTA and COMET trials influence your treatment of low-risk DCIS?
Clearly, postop RT can be avoided, but the pink elephant in the room is, can 5 years of endocrine therapy likewise be avoided? Treatment de-intensification requires addressing all aspects of therapy, particularly if one argues against adjuvant therapies for reasons of cost and toxicity. I can't reca...
Do you use either memantine or hippocampal sparing technique to preserve cognitive function when giving whole brain radiotherapy?
Dr. @Dr. First Last and I put together the response below:We use memantine and hippocampal sparing technique for all brain metastasis patients who are planning to receive WBRT. This is based off the recently published phase III trial NRG CC001 that found hippocampal avoidance WBRT plus memantine res...
